GAR-COUPLING.

To all whom it may concern Be it known. that; .I, WILLIAM. ,McCoN- WAY,J12, acitizen of the United States, re:

ing railway vehicles to each other, andis especially applicable to,tender coupler though'not limited thereto.

The principal objects of the invention are to provide simple andefficient means for preventing drooping of theflcoupler head and forconveniently and readily adjusting the coupler vertically to compensatefor the sagging of springs, wear of the wheels and other similar resultsof service aflectingthe' height of the coupler headabove the rails,

Generally stated, these ob ects are accom-,

plished by providing a coupler pocket and pivotally connecting the shankof a coupler thereto in such manner that the latteris capable ofswinging laterally to the desired extent, one of said membersbeingprovided with slots or recesses and the other of said members beingprovided with flanges which are adapted to enter said slots to therebymaintain the coupler in a plurallty of positions of vertical adjustmentabove the track rails.

In the drawings chosen for the purpose of illustrating my invention, thescope whereof is pointed out in the claims, Figure 1 is a plan view of atender coupler embodying my invention. Fig. 2 is a view showing thepocket member of the coupler in horizontal section on the line 52-52,Fig. 3, and illustrating the coupler in plan in one of its extremelaterally displaced positions. Fig. 3

is a side elevation of the coupler, the parts being inthe relativepositions illustrated in Fig. 1; and Fig. 45 is a detail Viewillustrating theimanner of assembling thecoupler in the coupler pocket.

In the drawings, 1 indicates the coupler and 2 is the coupler pocket ormember by which the coupler is attached to the tender or other railwayvehicle. These two mem-v Specification of Letters latent,"

here are preferably :pivotally connected means of a pivot pin 8 whichpasses through anapertureinearthearear endofthe coupler-shank andthroughcorresponding aper: tures near the inner end of the flaring recess ofthe pocket member into which'such coupler shank extends. .The rear end:of the coupler-shank-smay be formed, ifidesired,

with cylindrical bearing facesA- which'are concentric with the pivot pinopeningin the coupler shank and which are adapted to transmit the forceof ,bufiing shocks to, the correspondlngly, curved, bearing faces 5 uponthe .interior of the, pocket member 2.

Projecting laterally from the sides of the tively small dimensions andcorrespond.

ingly light in weight, while yet serving to permit. an extended lateralswinging of the coupler 1 and tosimultaneously engage the flanges 6 onbothsidesof the coupler shank, thereby insuring effective verticalsupport to the coupler throughoutgits entire arc of lateraldisplacement.

As a further means for preventing drooping'of the head of the coupler 1,the rear end of theshank of the coupler is preferably formed with arearwardly extending projection 8 which may beconveniently located inthe plane of the supporting flanges 6 projecting laterally from thesides of the coupler shank. This projection or flange 8, which is ofless height than that of the coupler shank, is adapted to enter and movewiththe coupler in either of the corresponding slots or recesses 9formed in the baseof the pocket member 2.

When the device is in service the laterally projecting flanges, 6 of thecoupler shank engage and are supported by the lowerfaces orfloors of:the particular slots 7 into. which the said flanges6 may have beeninserted in assembling the parts, while the rearwardly extendingprojection 8 at the end of the coupler shank engages the upper face orwall of the appropriate slot 9, means being thus provided both inadvance and to the rear of the pivot pin 3 for preventing the droopingof the coupler.

For convenience of eflecting temporary repairs while on the road, thecoupler pocket is, as shown, preferably formed with a flaring pocket soas to be capable of receiving any of the generally employed forms ofpivoted couplers and the usual form of shims commonly adopted foradjusting the height of the coupler above the rails.

I claim:

1. In a device of the character indicated, the combination with a pocketmember, of a coupler which is pivotally supported by said pocket member,means connected to said coupler and located in advance of the point ofpivotal connection of the pocket member and coupler for preventingdrooping of said coupler, and means to the rear of the said point ofpivotal connection for preventing drooping of said coupler.

2. In a device of the character indicated, the combination with a pocketmember, of a coupler adapted to be pivotally connected thereto in aplurality of positions of vertical adjustment, and means located to therear of the point of pivotal connection of the pocket member and couplerfor preventing drooping of said coupler, the same means serving toprevent drooping of the coupler in either of its said positions ofvertical adjustment.

3. In a device of the character indicated, the combination with a pocketmember, of a coupler pivotallyconnected thereto, said coupler beingprovided to the rear of its said point of pivotal connection with aprojection, and said pocket member being provided with a plurality ofslots each of which is adapted to receive said projection.

4. In a device of the character indicated, the combination with a pocketmember, of a coupler pivotally connected thereto, said coupler beingprovided with oppositely ex tending flanges, and said pocket memberbeing provided with slots adapted to receive the corresponding flanges.

5. In a device of the character indicated, the combination with a pocketmember, of a coupler pivotally connected thereto, said pocket memberbeing provided with a plurality of slots, and said coupler beingprovided with oppositely extending flanges which are adapted to enterthecorresponding slots of the pocket member to thereby vertically adjustthe said coupler with respect to said pocket member.

6. In a device of the character indicated, the combination with a pocketmember, of a coupler pivotally connected thereto, said pocket memberbeing provided with a plurality of slots, and the shank of said couplerbeing rovided with a plurality of laterally exten ing flanges which arewider at some points than at others and which are adapted to enter thecorresponding slots of said pocket member.

7 In a device of the character indicated, the combination with means forsupporting a coupler upon a railway vehicle, of a coupler having meanswhereby it may be pivotally connected to said supporting means andhaving a shank which is provided with a plurality of oppositelyextending projections that are adapted to overlap said supporting means.

8. In a device of the character indicated, the combination with meansfor supporting a coupler upon a railway vehicle, of a coupler havingmeans whereby it may be connected to said supporting means and having ashank which is provided with laterally extending projections that are ofless height than the height of the shank and that are adapted to overlapsaid supporting means.

9. In a device of the character indicated, the combination with a pocketmember, of a coupler pivotally connected thereto and adapted to beassembled therewith in a plurality of positions of vertical adjustment,said pocket member and the rear end of said coupler being provided withinterfitting means adapted to restrain vertical movement of the rear endof said coupler in its several positions of vertical adjustment.
